Definitions

  • the invention relates to a method for controlling a burner such as a concentrate or matte burner of a suspension smelting furnace such as a flash smelting furnace or a flash converting furnace as defined in the preamble of independent claim 1.
  • a burner such as a concentrate or matte burner of a suspension smelting furnace such as a flash smelting furnace or a flash converting furnace as defined in the preamble of independent claim 1.
  • the invention also relates to an arrangement for controlling a burner such as a concentrate or matte burner of a suspension smelting furnace such as a flash smelting furnace or a flash converting furnace as defined in the preamble of independent claim 9.
  • a burner such as a concentrate or matte burner of a suspension smelting furnace such as a flash smelting furnace or a flash converting furnace as defined in the preamble of independent claim 9.
  • WO 2012/151670 presents a burner and feed apparatus for flash smelter comprising a burner block that integrates with the roof of the furnace, the block having a nozzle opening therethrough to communicate with the reaction shaft of the furnace; a wind box to supply combustion gas to the reaction shaft through the nozzle opening, the wind box being mounted over the block; an injector having a sleeve for delivering pulverous feed material to the furnace and having a central lance within the sleeve to supply compressed air for dispersing the pulverous feed material in the reaction shaft, the injector mounting within the wind box so as to extend through the nozzle opening in the block, defining therewith an annular channel through which combustion gas from the wind box is supplied into the reaction shaft; and an injector surrounding structure extending from the wind box through the nozzle opening in the block.
  • the injector sleeve is supported by three mechanical screw actuators.
  • the actuators serve to adjust the height of the sleeve as well as to center the injector. They allow for precise raising and lowering of the sleeve when they are moved in unison so as to control the velocity of the combustion gas, and they allow for centering of the injector when they are controlled separately.
  • the centering can be automated by having three feedback sensors that provide feedback of the relative height of each of the actuators to the controller.
  • a disadvantage of this known burner is that it requires a quite complicated feedback sensor arrangement, because centering of the injector can affect the velocity of the combustion gas and vice versa. Objective of the invention
  • the object of the invention is to solve the above-identified problem.
  • the method for controlling a burner such as a concentrate or matte burner of a suspension smelting furnace such as a flash smelting furnace or a flash converting furnace of the invention is characterized by the definitions of independent claim 1.
  • the arrangement for controlling a burner such as a concentrate or matte burner of a suspension smelting furnace such as a flash smelting furnace or a flash converting furnace of the invention is correspondingly characterized by the definitions of independent claim 9.
  • the imaging apparatuses and the processing device provides for a simple feedback arrangement with great accuracy for determining centrality of the fine solids feeding device in the reaction gas feeding device so that the at least one first mechanical actuator, if needed can perform a centering action to ensure that a symmetrical annular reaction gas outlet opening is formed.
  • Separate second mechanical actuators may be provided for controlling the velocity of the combustion gas that flows through the annular reaction gas outlet opening.
  • Figure 1 shows a suspension smelting furnace
  • Figure 3 shows in cross section a burner in a second embodiment
  • a burner 1 such as a concentrate or matte burner of a suspension smelting furnace 2 such as a flash smelting furnace or a flash converting furnace and some embodiments and variants of the method will be described in greater detail.
  • the burner 1 comprises at least one, preferably by, two, three or four first mechanical actuator(s) 12 configured to center the fine solids feeding device 6 in the annular reaction gas outlet opening 9 so as to produce a symmetrical annular reaction gas outlet opening 9.
  • the fine solids feeding device 6 can for example be mechanically attached with at least one of said at least one first mechanical actuators 12, and at least a mechanical fastener allowing the fine solids feeding device 6 to pivot with respect to the reaction gas feeding device 5.
  • the method comprises producing images of the cross section of annular reaction gas outlet opening 9 with said at least two imaging apparatuses 13.
  • second mechanical actuators 16 comprising at least one of an electric motor, a servo motor, a hydraulic motor, a magnetic motor, and a pneumatic motor and a mechanical screw, a mechanical shaft, a rod, or the like driven by said at least one of an electric motor, a servo motor, a hydraulic motor, a magnetic motor, and a pneumatic motor.
  • the first mechanical actuator(s) 12 are preferably, but not necessarily, solely used for tilting the fine solids feeding device 6 with respect to a center line A of the burner 1.
  • the first mechanical actuator(s) 12 are preferably, but not necessarily solely configured to tilt the fine solids feeding device 6 with respect to the annular reaction gas outlet opening 9 of the annular reaction gas channel 8 of the reaction gas feeding device 5 of the burner 1.
  • the fine solids feeding device 6 surrounds the dispersion gas feeding device 7 so that an annular fine solids channel 10 is formed between the fine solids feeding device 6 and the dispersion gas feeding device 7, wherein the annular fine solids channel 10 having an annular fine solids outlet opening 11.
  • the burner 1, can as in the first embodiment shown in figure 2, comprise a dispersion gas feeding device 7 surrounded by the fine solids feeding device 6 so that the fine solids channel 10 is formed between the fine solids feeding device 6 and the dispersion gas feeding device 7, and so that the annular fine solids channel 10 is annular and so that the fine solids outlet opening 11 is annular.
  • At least two, preferably three or four imaging apparatuses 13 such as digital cameras are arranged symmetrically with respect to a center line A of the burner 1. Said at least two imaging apparatuses 13 are configured to produce images of the cross section of annular reaction gas outlet opening 9.
  • Said at least two imaging apparatuses 13 can be arranged at an upstream end wall 19 of the reaction gas feeding device 5.
  • Said at least two imaging apparatuses 13 can be arranged at least partly outside the burner and optical means such as lenses, objectives and/or mirrors can be provided for providing vision between the cross section of annular reaction gas outlet opening 9 and said at least two imaging apparatuses 13.
  • said at least two imaging apparatuses 13 can be arranged in the reaction gas channel 8 of the burner 1.
